“There are documented cases of slavery in Connecticut (went to high school there), Rhode Island”
Not sure what documents you are referring to, but Connecticut outlawed slavery in 1848. In 1840 Rhode Island only had 4 slaves left, all of who were free well before the Civil War started. I keep reading these posting about slaves in the North, which is of course possible, but since all the northern states had abolished slavery before the war began, whoever owned the slaves was committing a crime.
There must have been grandfathered in them because the local historical societies have record indicating slavery existed in such places as late as 1860.
Read my post...indentured for life is still slavery.
